Abstract
Provided are a system and method for identifying a peer-to-peer (P2P) application service. The method includes the steps of: (a) collecting an Internet protocol (IP) packet and generating a flow; (b) identifying the P2P application service on the basis of a port number using the generated flow; (c) when the P2P application service is identified in step (b), verifying the identified application service; (d) when it is verified that the identification is not correct, or the P2P application service is not identified in step (b), identifying the P2P application service on the basis of a payload; (e) when the P2P application service is identified in step (d) or it is verified in step (c) that the identification is correct, generating a SET table using a flow of the identified P2P application service; and (f) identifying the P2P application service for a flow not identified in either step (b) or step (d) using the SET table.
